Por isso, faz cada vez mais sentido pensar em "post-mortem":
"Get more out of post-mortems. Many people dislike project post-mortems. They’d rather talk about what went right than what went wrong. And after investing extensive time on the project, they’d like to move on. Structure your post-mortems to stimulate discussion. Example:Trechos retirados de "How Pixar Fosters Collective Creativity"
Pixar asks post-mortem participants to list the top five things they’d do again and the top five they wouldn’t do. The positive-negative balance makes it a safer environment to explore every aspect of the project. Participants also bring in lots of performance data—including metrics such as how often something had to be reworked. Data further stimulate discussion and challenge assumptions based on subjective impressions.
Because we’re a creative organization, people tend to assume that much of what we do can’t be measured or analyzed. That’s wrong. Most of our processes involve activities and deliverables that can be quantified. We keep track of the rates at which things happen, how often something has to be reworked, whether a piece of work was completely finished or not when it was sent to another department, and so on. Data can show things in a neutral way, which can stimulate discussion and challenge assumptions arising from personal impressions."
